My first build

[Buman]

I think it's a good buy for the price. I just bought a spikes tactical lower, just waiting for it to come in, and not because I don' like the Plumbcrazy lower, I just bought it because you can't have enough
But I think you will definetly like the plumbcrazy.

I just bought one with a CMMG upper!

Buman, before attending your carbine class in August, I'd suggest you have a complete back-up lower ready to go.

I think it's great you tried this as nothing teaches like experience. Not sure what I think of a polymer lower for a fighting carbine. Here's a link to a Plum Crazy link at the Fal Files-

is your hammer spring in correctly, the legs of the hammer spring need to be under not over the pin. The 3rd pic looks like its over.

Just want to say thanks. I had some misfires on a few rounds on a new builds first time to the range. After reading your post I discovered it too had the hammer spring installed wrong. Just fixed it and will be back to the range soon to see it that helped.
